Just down the street from my house is an agricultural field. In the winter part of it floods. It drains into a large wetland which is connected to San Francisco Bay. It attracts herons, egrets and ducks. A couple of days ago a great blue heron was hunting there. I stopped and watched to see what it would catch. I expected it to catch small fish. To my surprise it caught several crayfish. It will soon dry up. If you would like to purchase a print of this image click here.
